I will take C02 over a pump anyday. When I first started racing mtn. bikes back in the 80's, all I ever used was co2 and the reasons I did? More compact, much quicker inflation, no energy wasted on pumping like a fool just to get 30psi to name a few. 12 or 16gm cartridges will fill a tire fat.....32gm with a proper valve (inflater) can be used more than once.
A small pump is a good thing to carry, but co2 has never let me down.
